Propylene CAS 115-07-1 is an organic compound. Its main uses include the manufacture of plastics, chemical fibers, coatings, etc. It can also be used as a raw material for building materials, pharmaceutical intermediates, etc.
1. Basic concept of propylene
Propylene is a colorless gas with a chemical formula of C3H6, which belongs to the olefin class of organic compounds. It is an unsaturated compound with a double bond structure, which can undergo addition reactions, oxidation reactions and other reactions.
Propylene is a hydrocarbon compound extracted from petroleum and natural gas, and can also be obtained through cracking gas in the process of petroleum cracking. As the preparation process of propylene gradually matures, it has become one of the important raw materials for industrial production.
2. Preparation method of propylene
There are two main methods for preparing propylene: one is to obtain it through alkylation reaction, and the other is to obtain it through steam cracking method.
Alkylation reaction is the process of reacting acrylic acid or its derivatives with alcohols such as methanol and ethanol to produce propylene. The propylene prepared by this method has high purity, but the cost is high.
The steam cracking method is the process of decomposing alkane compounds under high temperature and pressure to produce propylene. This method is low in cost, but the purity is relatively low.
3. Uses of propylene
1. Plastic manufacturing: Propylene is the main raw material for the production of polypropylene, which is widely used in plastic products, fibers and other fields.
2. Chemical fiber: Propylene can be used to make synthetic fibers such as polypropylene and acrylic. These fibers have antibacterial and antistatic properties and are used in clothing, medical devices and other fields.
3. Coatings: Propylene can be used as the basic raw material for coatings, used to produce indoor and outdoor wall coatings, automotive coatings, etc.
4. Building materials: Propylene can be used as a raw material for building materials, used to produce insulation materials, waterproof materials, etc.
5. Pharmaceutical intermediates: Propylene can be used to synthesize intermediates for a variety of drugs, such as antibiotics, analgesics, etc.
4. Conclusion
As an important organic compound, propylene has a wide range of application prospects. From plastics, chemical fibers, coatings to building materials and pharmaceutical intermediates, propylene plays an irreplaceable role. With the development of science and technology, the use of propylene will continue to expand.
